What is a Resistor? An electric resistor is a two-terminal passive component specifically used to oppose and limit current. A resistor works on the principle of Ohm’s Law which states that voltage across the terminals of a resistor is directly proportional to the current flowing through it. Ohm’s‚Law: v=IR where V is the voltage applied across resistor‚ I is the current flowing through it‚ and R is the constant called resistance. The unit of resistance is ohms. Types

Title: Resistors in Series and Parallel Date: 17/7/05 Aim: The aim of this experiment is to compare the predicted and actual resistance in a circuit of resistor combinations in series and in parallel. Background: A resistor is an electrical component/device that has electrical resistance. Resistors can be used in electric circuits for protection of components‚ voltage division or current control. In an ideal resistor the resistance remains constant regardless of the applied voltage or current

Controlled Assessment ISA (PU 2.5) Light Dependent Resistors (Section 1) 1. Write down your hypothesis. Explain why you made this hypothesis. Hypothesis: When it is day there is more light hitting the LDR and so its resistance decreases and the light turns off. When it is night there is less light so the LDR has higher resistance and the light turns on. Explanation: When light shines on a Light Dependent Resistor‚ electrons are released and the current can get larger. So as the light intensity increases

LDR Circuit Diagram: Here is the schematic for the circuit: Light Dependent Resistors Light Dependent Resistors (LDR) are also called photoresistors. They are made of high resistance semiconductor material. When light hits the device‚ the photons give electrons energy. This makes them jump into the conductive band and thereby conduct electricity. A photoresistor or light-dependent resistor (LDR) or photocell is a light-controlled variable resistor. The resistance of a photoresistor decreases

Define the following: RESISTOR A resistor is a component of a circuit that resists the flow of electrical current. It has two terminals across which electricity must pass‚ and it is designed to drop the voltage of the current as it flows from one terminal to the other. Resistors are primarily used to create and maintain known safe currents within electrical components. Resistors are coated with paint or enamel‚ or covered in molded plastic to protect
